# Alpha Max Open Usd

`POST /v1/me/accounts/{account_id}/alphas/{deploy_id}/max-open-usd`

## Request

- Base URL: `https://api.quantradin.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.quantradin.com/v1/me/accounts/{account_id}/alphas/{deploy_id}/max-open-usd`
- Auth: none declared

MAX OPEN $ (2026-08-06) — set (or clear with null) this bot's OWN cap on how
much money it may have committed across all its open positions at once. It
OVERRIDES the desk cap; cleared → the bot follows the desk cap (or is uncapped
if that is unset too).

Composes with the per-trade cap rather than replacing it: `max_usd_per_trade`
bounds ONE order, this bounds the whole bot, and the desk's buying power bounds
everything. A trade must pass all three. A LIVE-FILL knob — it never touches the
verdict. Owner/desk-pair scoped (404 cross-desk, via _owned_deployment), audited
like the other per-bot edits.
